Analyses of Reinforcement Technology and Stability of One Deep Foundation Fit Engineering

The deep foundation fit of Xin Ming He building was reinforced by soil nail, shot concrete and steel bar mesh, and the calculated pressure per unit area of soil nail is about 83.48kN which is larger than the largest lateral earth pressure which is about 59.55kN, from which it can be known that the foundation fit is stable. Meanwhile, the 3D-σ finite element program was used to simulate axial force of soil nail, lateral displacement of foundation fit and surface displacement, and their values are all small which show that the foundation fit is stable.
